BACKGROUND: In children, perianal abscesses have a good prognosis and often heal with age. However, some perianal abscesses are refractory to treatment and remain as fistulas-in-ano. Treatment with a Surgisis Anal Fistula Plug® has been reported as a new method of treatment for fistulas. In adults, the plug has been reported to cause little pain and have a high cure rate, but there have been no reported cases of its use in children. PURPOSE: This study was designed to analyze the efficacy of the plug for closure of refractory fistulas in children...

BACKGROUND: Internal hernia (IH) is a common complication of laparoscopic Roux-en-Y gastric bypass (LRYGB). Little large-volume data exist on how to handle the mesenteric defects during LRYGB. This study evaluated long-term follow-up (5.5 years) of 2443 patients with primary closure of the mesenteric defects with a stapling device at LRYGB, in comparison with a non-closed group from the same centre. METHODS: All patients (N = 4013) undergoing LRYGB over a 10-year period (2005-2015) at a single institution were evaluated...

BACKGROUND: Numerous conventional wound reconstruction methods, such as wound undermining with direct suture, skin graft, and flap surgery, can be used to treat large wounds. The adequate undermining of the skin flaps of a wound is a commonly used technique for achieving the closure of large tension wounds; however, the use of tension to approximate and suture the skin flaps can cause ischemic marginal necrosis. The purpose of this study is to use elastic rubber bands to relieve the tension of direct wound closure for simultaneously minimizing the risks of wound dehiscence and wound edge ischemia that lead to necrosis...

OBJECTIVES/HYPOTHESIS: Current rhinologic practice is devoid of minimally invasive procedures dedicated to the treatment of ethmoid sinusitis to improve ventilation and topical drug delivery. We have recently described a handheld spiral punch to create minimally invasive ethmoid punch sinusotomy (EPS) sites into the ethmoid bulla and basal lamella, which significantly increased irrigant access to the ethmoid sinuses in cadaver models. Here, we conducted a clinical feasibility study to determine the initial safety evaluation of EPS in chronic rhinosinusitis without polyposis (CRSsNP) patients with active ethmoid disease...

The portacath is commonly used in the treatment of oncology patients. Although common long-term complications of these devices, such as infection and thrombosis, have been widely reported, venous-airway fistula due to port placement is an extremely rare and poorly understood complication. We report a case of a 56-year-old female with pancreatic adenocarcinoma whose portacath was complicated by the development of an azygo-bronchial fistula with a concomitant aspergilloma. Herein is the first reported case of successful venous-airway fistula closure obtained through silicone stenting...

Endoscopic submucosal dissection is established as a curative endoscopic method for gastrointestinal epithelial neoplasms with a high possibility of complete en bloc resection; however, postoperative adverse events of bleeding and delayed perforation remain. To prevent or minimize them, several techniques for endoscopic mucosal closure have been introduced, such as using endoscopic clips, combined use of hemoclips and supplement devices, and specially designed endoscopic suturing devices. Furthermore, endoscopic full-thickness suturing technique for gastrointestinal wall defect has been developed based on the concept in natural orifice transluminal endoscopic surgery and endoscopic full-thickness resection...

BACKGROUND: Colorectal cancer is common in humans where treatment involves surgical removal of the cancerous part of the intestines. In the anastomosis procedure a purse-string suture may be time consuming to perform. The aim was to replace the purse-string suture, to develop and test a self-locking loop for temporary sealing of the lumen in colon anastomosis. METHODS: A new device, a flexible band with a locking mechanism was constructed, the I-Tie(®). Small protrusions, designed for increased friction between device and tissue, were added to one side of the flexible band in order to enhance the grip at closure of the loop around tissue...

Two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) are of great interest for applications in nano-electronic devices. Their incorporation requires the deposition of nm-thin and continuous high-k dielectric layers on the 2D TMDs. Atomic layer deposition (ALD) of high-k dielectric layers is well established on Si surfaces: the importance of a high nucleation density for rapid layer closure is well known and the nucleation mechanisms have been thoroughly investigated. In contrast, the nucleation of ALD on 2D TMD surfaces is less well understood and a quantitative analysis of the deposition process is lacking...

OBJECTIVES: To describe the feasibility and safety of the Hopscotch Technique, a novel method to close paravalvular leaks. BACKGROUND: Successful closure of paravalvular leaks requires the complete seal of irregular defects, frequently interrupted by remaining sutures or tissue that converts a large defect into a complex series of contiguous smaller defects. Successful treatment with devices placed in a single space is impossible with constrained appearance and significant residual leak; therefore, new techniques to deploy smaller devices in the correct location are needed...

Tricuspid valve (TV) injury following transcatheter closure of perimembranous ventricular septal defect (PMVSD) with Amplatzer ductal occluder I (ADO I), requiring surgical repair, is rare. We report two cases of TV tear involving the anterior and septal leaflets following PMVSD closure using ADO I. In both the patients, the subvalvular apparatus remained unaffected. The patients presented with severe tricuspid regurgitation (TR) 6 weeks and 3 months following the device closure. They underwent surgical repair with patch augmentation of the TV leaflets...

: The immediate tissue microenvironment of implanted biomedical devices and engineered tissues is highly influential on their long term fate and efficacy. The creation of a long-term anti-inflammatory microenvironment around implants and artificial tissues can facilitate their integration. Macrophages are highly plastic cells that define the tissue reactions on the implanted material. Local control of macrophage phenotype by long-term fixation of their healing activities and suppression of inflammatory reactions are required to improve implant acceptance...

BACKGROUND: Glaucoma is the primary cause of irreversible blindness worldwide associated with high intraocular pressure (IOP). Elevated intraocular pressure will affect the normal aqueous humor outflow, resulting in deformation of iris. However, the deformation ability of iris is closely related to its material properties. Meanwhile, the passive deformation of the iris aggravates the pupillary block and angle closure. The nature of the interaction mechanism of iris deformation and aqueous humor fluid flow has not been fully understood and has been somewhat a controversial issue...

Left atrial appendage closure (LAAC) is a promising site-directed therapy for stroke prevention in patients with non-valvular atrial fibrillation (AF) who are ineligible or contraindicated for long-term oral anticoagulation. A variety of LAAC modalities are available, including percutaneous endocardial occluder devices such as WATCHMAN(TM) (Boston Scientific Corp., Marlborough, MA, USA), and an ever-increasing body of evidence is helping to define the optimal use of each technique. Similarly increased experience with LAAC has revealed challenges such as device-related thrombi and peri-device leaks for which the long-term significance and appropriate management are areas of active investigation...

Paravalvular leakage (PVL) occurs in 6%-15% of cases after surgical heart valve replacement. A percutaneous approach is increasingly used to close PVLs as an alternative to repeat surgery. Computed tomography (CT) can be used for simulation of fluoroscopic cardiac anatomy. This technique allows preprocedural definition of optimal C-arm angulations and PVL localization in reference to fluoroscopic views. It is very helpful for guidewire crossing of the PVL and positioning of the closure device. We report a case with the first use of dedicated software for fluoroscopic simulation (FluoroCT) in transcatheter mitral PVL closure...
